e2e: split e2e tests into different suites
This commit splits the e2e tests into different suites that all reuse helper functions from the lib.sh file. This split ensures that the tests within a suite can all have the same setup, e.g. all tests depending on a full-mesh will be set up with a full-mesh, and is resilient against changes in test ordering.
